I To all whom it may concern:

Be it known that I; REUBEN B. THOMPSON, a citizen of the United States, residing at Cohoes, in the county of Albany, State of New York, have inventedcertain new and useful Improvements in PressenFeet for Sewing-Machines, of which the following is 1 a description, reference being had to the ac point in advance of the needle opening,-

wherein the said presser foot is divided longitudinally tions extendlngfon opposite sides of said so that one section may vertically yiel independent of the other,

. mounted on the A further object of the invention is to provide a presscrifoht of the above character wherein the startle e y trimming blade is I 3 1113606011 of the presser f, t bi drdes operate a [nner end of the gui in slot to sever he SflQ'iOIlS pasing alqn the 5105:

This spring ro ects u wardlyand then is bent to pro ect over t e shank 10 of the auxiliary presser foot and movable trimming blades operating at the inner end of Mid slot to sever fabric sections passing there along.

3. The combination of a presser foot having a fabric uiding slot extending rearwardly from tlie front end thereof and having a needle opening in rear of and in line with said slot, said presser foot being divided longitudina ly to form independent foot sections respectively extending on opposite sides of said slot, a prcsser bar, means for rigidly connecting one of said sections to the presser bar and means for supporting the other section whereby the same may vertically yield independently of the first named section and a trimming mechanism including a horizontally disposed stationery blade carried by the section rigidly secured to the presser bar and a horizontally disposed movable'blade; said trimming lades operating at the inner ends of said slot to sever fabric sections passing there along.

4:. The combination of a presser foot having a fabric guiding slot extendingrearwardly from the front end thereof and having a needle opening in rear of and in line with said slot, said presser foot being divided longitudinally to form independent foot sections respectively extending on opposite sides of said slot, means for supporting said sections whereby one section may vertically yield independently of the other section, a trimming mechanism including horizontall disposed and relatively movable trimmlng blades operating at the inner end of said slot to sever fabric sections passing there along, and a strip deflector projectin across the guiding slot, the front end 0 said strip deflector being spaced above the yielding section of the resser foot, so as to permit free movement t ereof.

5. The combination of a presser foot having a fabric guiding slot extending rearwardly from the front end thereof and havin a needle opening in rear of and in line with said slot, said presser foot being divided longitudinally to form. independent foot sections respectively extending on opposite sides of said slot, a presser bar, means for rigidly connecting one of said sections to the presser bar and means for supporting the other section whereby the same may vertically yield independently of the first named section, a trimm'mg mechanism including a horizontally disposed stationary blade carried by the section rigidly secured to the presser bar and a horizontally disposed movable blade, said trimming blades operating at the inner ends of said slot to sever fabric sections passing there along, and a strip deflector carried by the section of the foot rigidly attached to the presser bar and projecting across said uiding slot, the front end of said strip de ector being spaced above the yielding section of the presser foot, so as to permit free movement thereof.

In testimony whereof I afiix my signature in the presence of two witnesses.
